How to create a serial object using web app server?

I have deployed an app using the App Designer in Matlab and compiled it as a web app.

This app can conect with a device through serial comunication. The user interface has a dropdown that displays all available serial ports, and the app will connect with the selected device.

The problem is when I run the app on the Matlab web server: the devices shown in my dropdown are the available serial ports in the server, rather than the serial ports from the computer that access the server.

How could I change this?
